Background to Risks

Email is part of the lifeblood of Rose Bruford College, but accidental or deliberate misuse can have a number of serious impacts upon the college. Here are several potential risks with examples using cases that have been publicised:

Risk - incorrect Business Use by Staff or Student
With click of mouse employee can accidentally send an email either internally or externally to the organisation that results in embarrassment to management, discloses confidential information to the wrong recipient, or results in an unauthorised contractual commitment. A libellous email can also be used as part of incriminating evidence during legal proceedings against the organisation by an employee, or by an external party. The impacts to the college could include settlement or court fines, loss of customers or potential clients or damage to public reputation.

Risk - Inappropriate Personal Use by Staff or Student
An email that was of a personal but sensitive nature was forwarded to other member of staff or student, and external email addresses. For example, a distasteful joke or remark about someone sent is to a friend, which is subsequently forwarded to journalists and is published. The college’s reputation could be severely damaged – depending on type of business and contents of email.

Risk - Offensive Content from Staff, Students or Outsiders
Distribution of porn or otherwise offensive content can affect the moral of staff, result in serious embarrassment to the college and its management with potential loss of students and damaged reputation. The college could be embroiled in lengthy and costly legal cases which also use up staff and management resources.

Risk - Chain Emails, Hoaxes, SPAM and forged emails
Chains and Unsolicited emails (e.g. SPAM) affect staff and students productivity, can be annoying and affect the operation of email services and network resources. Emails with large attachments such as images or video clips also impact the operation of the email service.
Up to 65% of emails are SPAM and significant resources are spent by ICT staff dealing with this on a daily basis. Forged emails can lead a member of staff or student carrying out an activity that could disclose confidential information or otherwise jeopardise the college. Email scams can result in impact to staff and student productivity, and scams directly targeted at certain types of business could lead to disclosure or other types of losses by students or members of its staff.

Risk - Corruption by Malicious Content
Email continues to be one of the main sources for the transfer of malicious software around the Internet, affecting the availability and integrity of workstations and severs. Email worms may contain or cause the download of software that results in Distributed Denial of Service (DDoS) attacks against other Internet websites, or otherwise uses the resources of one company’s information systems to launch attacks on another.  The college reputation would be badly damaged by such an incident; the organisation could be sued and may have to pay for remedial work to its own systems.

Risk - Use of Personal Email Systems
College email that is created on, forwarded to or otherwise stored on email systems outside of the college’s control will be bypassing many of the controls implemented to meet the email policy requirements, including email disclaimer statements, and cannot be monitored by the college.

Risk - Copyright Infringement
Software executables that are distributed via email either into or out of Rose Bruford College may result in an infringement of copyright rules. This could result in embarrassment to Rose Bruford College and large fines.
